According to P. Huvelin the lex Atinia read as follows: Quod subruptum erit, nisi in potestatem eius, cui sub-ruptum est, revertatur, eius rei aeterna auctoritas esto. This reconstruction is no doubt fairly accurate. What, then, is the relation of the lex Atinia to the XII Tables? For, as it appears from the sources, it was already the XII Tables that excluded a res furtiva from usucaption.
